multiselecting objects does not show differing relation membership correctly in the sidebar

[maizzerna]

multi-selecting objects does not show differing relation membership correctly in the sidebar (like it does for tags).

Steps: select one object which is member of one specific relation and some which is no member of any relation.

Actual: relation membership is shown if one object (although the others are not) is a member ("position" column shows a single number.

Expected: relation membership (here: "position" for consistency with the tag list) should be indicated as <differing> or x, no (x being a number).

Workaround: the user needs to think. If the current object selection is more than one but only one number in the "position" column is shown then some are not a member.

Though I understand your problem, I still like the numbers are useful as it is a nice hint about the relation's order.

skyper, yes the numbers are useful and they should stay. But I think there should be a indication that one (or several) of the selected objects are not a member of the relation. I noticed this display problem when I selected several meadows inside a forest which I wanted to tag as "inner".

In 6652/josm:

fix #9525 - multiselecting objects does not show differing relation membership correctly in the sidebar

For instance, positions are displayed as 48-49,91,✗.
